Lighting — FAQ
How many lumens do I need for a 2-car garage?
Target 8000-12000 total lumens for a 20x20 ft garage. Two 4400-lumen fixtures provide excellent general illumination, while four fixtures eliminate shadows for detailed work. Measure your space—low ceilings need fewer lumens than high bays due to light dispersion.
Is 5000K or 6500K better for garage lighting?
5000K matches natural daylight and renders colors accurately—ideal for painting, staining, or electrical work. 6500K appears slightly brighter but casts a blue tint that distorts colors. For mixed-use garages, 5000K offers the best versatility and eye comfort.
Can I plug shop lights into a standard outlet?
Yes, most budget shop lights are plug-in rated for 120V outlets. Check amperage—LEDs under 60W draw less than 0.5 amps, so you can safely link 4-6 units on a 15-amp circuit. Avoid extension cords; use direct outlet connections for safety.
What does ETL certified mean?
ETL (Edison Testing Laboratories) certification means the fixture meets North American electrical safety standards equivalent to UL. It’s tested for fire hazards, shock risks, and component quality. Always choose ETL or UL listed lights for garage use where dust and temperature extremes increase risks.
How much will I save switching from fluorescent to LED?
A 40W LED replacing a 250W fluorescent saves $35-45 annually per fixture (assuming 8 hours daily use at $0.12/kWh). LEDs last 50,000+ hours versus 10,000 for fluorescents, eliminating replacement costs. Payback period is typically 6-12 months for budget LEDs.
Do reflector lenses really make a difference?
Reflectors concentrate light downward, increasing intensity on work surfaces by 10-15%. This helps in high-ceiling installations but reduces side illumination. For ceilings under 10 feet, standard diffused lenses provide better overall coverage. Choose reflectors for task lighting, diffusers for ambient light.
